AdS Celestial Symmetries: from Ambitwistor charges to CFT Light-Ray Operators
Alex Goodenbour, Adam Kmec, Lionel Mason +1
The algebra is the cosmological-constant deformation of the celestial symmetry algebra of gravity, providing an infinite-dimensional extension o…
Decompactification and the Flat-Space Limit of AdS S Master Correlators
Burkhard Eden, Paul Heslop, Harshal Kulkarni +3
We study the flat-space limit of AdS/CFT holographic correlators while accounting for the simultaneous decompactification of the internal S. We show that this limit is…
Self-Dual Yang-Mills in AdS
Simon Heuveline, Romain Ruzziconi, Ahmed Sheta +1
Quantum Yang-Mills theory in Euclidean AdS with Neumann boundary conditions is studied as a function of the complex couplings $\frac{1}{g_\pm^2} \equiv \frac{1}{g^2}\mp \frac{i…
Observing Massive Scattering from Null Infinity
Walker Melton, Kyrill Michaelsen, Romain Ruzziconi
Because massive particles asymptote to timelike rather than null infinity, current flat space holographic proposals such as celestial or Carrollian holography struggle to describe…
Quasi-Local Celestial Charges and Multipoles
Adam Kmec, Lionel Mason, Romain Ruzziconi
We extend Penrose's quasi-local mass definition to include higher-spin charges associated with the celestial symmetries and relate them to traditional definitions o…
Carrollian Physics and Holography
Romain Ruzziconi
This report reviews key developments in Carrollian physics with an emphasis on their role in the emerging framework of holography in asymptotically flat spacetimes. We begin by int…
On Carrollian and Celestial Correlators in General Dimensions
Harshal Kulkarni, Romain Ruzziconi, Akshay Yelleshpur Srikant
Carrollian holography is a framework for flat space holography, suggesting that gravity in asymptotically flat spacetime in dimensions is dual to a conformal Carrollian field t…
S-algebra in Gauge Theory: Twistor, Spacetime and Holographic Perspectives
Adam Kmec, Lionel Mason, Romain Ruzziconi +1
The celestial -algebra arose from a reinterpretation of collinear limits of the Yang-Mills S-matrix as OPEs in celestial holography. It was subsequently represented via asymptot…
Towards a Flat Space Carrollian Hologram from AdS/CFT
Arthur Lipstein, Romain Ruzziconi, Akshay Yelleshpur Srikant
Finding a concrete example holography in four dimensional asymptotically flat space is an important open problem. A natural strategy is to take the flat space limit of the celebrat…
Holographic Carrollian Currents for Massless Scattering
Romain Ruzziconi, Amartya Saha
We show that the Ward identities of a Carrollian CFT stress tensor at null infinity reproduce the leading and subleading soft graviton theorems for massless scattering in the bulk.…
Differential Equations for Carrollian Amplitudes
Romain Ruzziconi, Stephan Stieberger, Tomasz R. Taylor +1
Differential equations are powerful tools in the study of correlation functions in conformal field theories (CFTs). Carrollian amplitudes behave as correlation functions of Carroll…
Celestial charges from a twistor action
Adam Kmec, Lionel Mason, Romain Ruzziconi +1
The celestial symmetries in asymptotically flat spacetimes have a natural geometric interpretation on twistor space in terms of Poisson diffeomorphisms. Using this…
Carrollian Amplitudes from Holographic Correlators
Luis F. Alday, Maria Nocchi, Romain Ruzziconi +1
Carrollian amplitudes are flat space amplitudes written in position space at null infinity which can be re-interpreted as correlators in a putative dual Carrollian CFT. We argue th…
Carrollian Amplitudes and Celestial Symmetries
Lionel Mason, Romain Ruzziconi, Akshay Yelleshpur Srikant
Carrollian holography aims to express gravity in four-dimensional asymptotically flat spacetime in terms of a dual three-dimensional Carrollian CFT living at null infinity. Carroll…
